PoC is also x86_64 only and not arm.

  • Thanks! Will give it a try a bit later.

    (HN algorithms have killed some of your comments, perhaps because you posted the same URL too many times from a relatively new account? I’ve vouched for you, but keep in mind that it triggers antispam.)

    Edit: naturally, no luck:

      $ ./exploit /system/bin/ping
      [+] target:    /system/bin/ping
      [+] payload:   2112 bytes (528 iterations)
      socket(AF_ALG): Permission denied
      patch_chunk failed at offset 0
    

    Guess AF_ALG is just disabled on Android kernel builds. Though maybe it’ll work on other devices!
